The defer syntax feels wrong to me, I think because it looks like a function call but doesn't behave like one (because it assigns to its arguments). If it behaves different then it should look different. Since it creates a continuation, perhaps it should resemble the syntax for creating a function, like this: await resolve "host.com", (ip, err) ~> console.log "#{ip} #{err}" or this: await resolve "host.com", (ip, err) <- console.log "#{ip} #{err}" Introducing an operator like this would also avoid some name collisions. And does the callcc really have to be able to assign to things? Make it work just like a formal parameter list, and then you can actually compile it into one, avoiding all that pass-by-reference hoopla. The autocb thing is even weirder. Magic variable names? I've never heard of a language that resorted to this. Why not just some new syntax to mark a parameter as the callback? Perhaps some postfix modifier, to match the splat syntax? resolve = (host, callback <-) -> ... return ip, err or overload a keyword? resolve = (host, return callback) -> ... return ip, err
